Contraindications

So what are contraindications? They let you know when not to use the system; you may
hurt yourself or damage the system. Remember, if used during certain situations, the risk of
use may clearly outweigh any potential benefit. Within the chapters, contraindications are in
purple boxes.

MRI/CT/Diathermy

Do not wear the Dexcom G5 Mobile (sensor, transmitter, and receiver) during Magnetic
Resonance Imaging (MRI), Computed Tomography (CT) scan, or high-frequency electrical
heat (diathermy) treatment.
The Dexcom G5 Mobile has not been tested during MRI or CT scans or with diathermy
treatment. The magnetic fields and heat could damage the components of the Dexcom G5
Mobile, which may cause it to display inaccurate blood glucose readings or may prevent
alerts.

Medications

Taking medications with acetaminophen (such as Tylenol or Excedrin Extra Strength) while
®
wearing the Dexcom G5 Mobile may inaccurately raise the glucose readings generated by the
Dexcom G5 Mobile. The level of inaccuracy depends on the amount of acetaminophen active
in your body and is different for each person. Do not rely on continuous glucose monitoring
(CGM) data produced by the Dexcom G5 Mobile if you have recently taken acetaminophen.
Warnings
What are warnings for? They outline important hazard information, describing any serious
and/or life-threatening situations, their consequences, how to avoid danger while using the
system and how to protect the system from harm.

Sensor Fractures

Do not ignore sensor fractures. Sensors may fracture or detach from the sensor pod on
rare occasions. If a sensor breaks and no portion of it is visible above the skin, do not
attempt to remove it. Seek professional medical help if you have symptoms of infection or
inflammation—redness, swelling, or pain—at the insertion site. If you experience a broken
sensor, please report this to our Technical Support department at 1.888.738.3646 (toll free)
or 1.858.200.0200.
